| Abstract: | In this article a method was presented for synthesis of propylene glycol monoethyl ether from propylene oxide and ethanol by catalytic distillation and with NKC 1 molecular sieve catalyst.The influences of operating pressure,feed flow rate and mole ratio of ethanol to propylene oxide in feed on the conversion of propylene oxide,and yield and selectivity of propylene glycol monoethyl ether were inspected.Suitable operating conditions for this process were given. |
